11.   In a decade of mechanical defensive systems and dwindling scores, the Leafs blew like a crisp, cool breeze out of Canada, a brisk wind of change.

12.   Indeed, the electronics revolution has dramatically simplified small scale engine production by allowing microprocessors to do the work of exceptionally complicated and delicate mechanical systems.

13.   Inflatable structures are much lighter, less complicated and cheaper than conventional mechanical systems, officials said, and should be more reliable because they have fewer moving parts.

14.   Invest in good-quality paint, mechanical systems and windows and doors.

15.   Inside, a hardware cage houses irrigation and mechanical systems.

16.   Instead, they are built around networks of simple sensors, switches and mechanical systems that respond to analog signals like lightwaves, heat or sounds.

17.   It took him months to create a prototype of the mechanical system and to adapt freely available software source code for solving the puzzle.

18.   Manufacturers at the turn of the century were learning that by filtering air and stabilizing temperature, mechanical systems improved the environment for products . . . and people.

19.   Many have worked for the FAA for decades and are familiar with computer and mechanical systems that are no longer in use elsewhere.

20.   Mechanical systems become obsolete.
